Embodiment Construction

[0021] For ease of description, several terms mentioned in this article need to be explained and illustrated. However, it should be noted that such explanation is only for the purpose of illustration, and is not intended to limit the present invention in any form.

[0022] First of all, the data referred to in this article can be any type of data, for example, it can be the dot matrix data of an image, the sampling data of a piece of audio, or compressed data, such as JPEG data. Moreover, before the data is processed, it is not necessary to know in advance which type of data it belongs to. The data search mentioned above refers to the process of searching for data similar to the pattern data from the source data. Therefore, the pattern data is used as comparative standard data, and the searched data is called matching data.

[0023] In order to take into account the hit rate and search efficiency, the search method of the present invention sets two similarity thresholds and t...

Abstract

A fussy data search method and device comprises the matching of source and mode data based on the comparison of first comparing step length and the first similarity threshold value, then the second one if the first passes, with the first step length no longer than the second one. It is simple, easy with consideration of the speed and accuracy.

Description

technical field [0001] The invention relates to a data search method, in particular to a fuzzy data search method and device. Background technique [0002] With the advent of the information age, the amount of data that needs to be processed has grown enormously. How to efficiently process these data has become one of the urgent problems to be solved. In data processing, it is often necessary to search for the required data among massive amounts of data, so how to quickly and accurately search and locate data is crucial to the efficient processing of data. [0003] There are a variety of data search methods in the prior art, but some of these methods are too inefficient, some have a low hit rate, and some are too complicated to implement. And some data search methods must know in advance what kind of data the data is, and then can make statistics based on some unique information of this kind of data. For example, image data can be searched based on parameters such as colo...
